This standard applies to fixed resistance networks where each resistor can be measured separately within the range of 1-1. In any circuit that allows measurement of each independent resistor, these resistors can be independently separated or interconnected. Note. Another independent sub specification that includes complex networks is GB 12276-90 (idt IEC 115-7:1984/QC 400500) "Fixed Resistors for Use in Electronic Equipment - Part 7; Sub specification; Fixed Resistor Networks where each resistor cannot be measured separately". The purpose of this standard is to specify the priority ratings and characteristics of such resistance networks, and to select applicable quality assessment procedures, testing and measurement methods, as well as general performance requirements, from the GB/T 5729-94 (IEC 115-1; 1982) "Fixed Resistors for Electronic Equipment: Part I: General Specification". The test severity and requirements specified in the detailed specifications formulated by referencing this standard must be equal to or higher than the performance level specified in this standard, and reducing the performance level is not allowed. 1.3 Relevant Documents GB/T 2471-1995 Series of Preferred Numbers for Resistors and Capacitors (idt IEC 63-1:1963) GB/T 5729-94 Resistors for Use in Electronic Equipment Part l: General Specification (idt lEC 115-1:1982) lEC 68 Basic Environmental Testing Procedures lEC 410 (1973) Sampling Plan and Procedure for Count Inspection IECQ/QCO01001 (1986) IEC Electronic Component Quality Assessment System (IECQ) Basic Regulations IECQ/QCO01002 (1986) IEC Electronic Component Quality Assessment System (IECQ) Procedure rule note: Except for IEC 68, which adopts the version specified in the corresponding test clauses of the general specification, all other standards mentioned above adopt the current version
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsBaijian and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
